arm64: dts: rockchip: rk3588s-tablet: fix charger ic output otg current limit problem

Browse Source 
At present, the charger ic output otg current limit is 500mA, the
high-current usb device (for example, usb3.0 hard disk) cannot work
normally in Type-C0, such as disconnection and reconnection. According
to the requirements of the usb3.0 protocol, the minimum vbus current
limit is 900mA. We set the charger ic output otg current limit to 900mA,
and the video playback in the usb3.0 hard disk is still unstable.
The rk3588-evb Type-C vbus current limit is about 1.44v, the usb3.0 hard
disk can work stably, so the rk3588s tablet output otg current limit is
configured to 1.5A.
